SPECIFICATION forming" part of Letters Patent No. 254,725, dated March '7, 1 882.

Application filed September 24, 1881. (No model.)

To all whom it may concern v Be it known thatwe, JEssE Woon THAMES and Bonner IRvIN RILEY, of Greenville, in the county of Butler and State of Alabama, have invented a new and useful Improvement in Cotton-Gin Attachments, and we do hereby declare that the following is a full, clear, and

exact description of the same, reference being had to the accompanying drawing, forming part of this specification.

Our invention relates to an attachment for cotton-gins whereby cotton while being ginned is cleaned of all sand, dirt, motes, and trash and it consists of a series of adjustable slats, connected together and journaled in a frame, the latter and its movable slats forming the bottom part of the gin-flue immediately under the brush-cylinder, whereby the dirt and trash in the cotton being ginned are drawn by the current of air generated by the brush-cylinder through the openings between the movable slats into a receptacle under them.

Our invention furtherconsists in certain details of construction, hereinafter more fully set forth.

In the accompanying drawing,a represents the saw-cylinder, b the brush-cylinder, and c the flue, of a cotton-gin of ordinary construction.

11 represents our improved attachment or cleaner, which is placed immediately under the brush-cylinder and three or four inches from it, the upper part of the cleaner extending out at the back part of thegin and forming the bottom part of the fine.

h h represent the tapering side boards of the cleaner, the narrow ends of said tapering side boards being arranged at the back partof the gin and above the broader front ends of the sides, and the cleaner forming the inclined bottom of the flue.

irepresents an inclined transverse hoard, connecting the ends ofthe tapering side boards,

h h, at the back part of the cleaner.

is k represent a series of movable slats, which are provided with journals at their ends, havin g their bearin gs in circular holes made in the side boards, h h, and adapted to rock therein like the slats of a window-blind, and are beveled, so as to fit closely upon each other when the slats are shut.

1 represents arod or bar passing transversely under the middle of the slats, and provided with a series of staples, m, one opposite each slat, which engage with a series of eyes, n, inserted one in each slat, whereby the rod is connected with the movable slats, whichmove in unison, and can be closed or opened by moving back and forth the rod Z.

0 represents a screw secured to the upper end of the rod 1, and passing through a hole in the end board, t, of the slat-frame.

19 represents aspiral spring, encircling the screw, one end of the spring bearing against the upper end of the rod l and its opposite end hearing against the end board, i,.ot" the slatframe, the tension of the spring being exerted to close the slats.

t represents a thumb-nut on the end of the *screw. By screwing up the not the slats are opened, and by turning the nut in the opposite direction the slats are closed.

q represents acenter board or air-arrester lying under the slats, and having its ends secured to the inner faces of the side boards, h h. The function of this bar is to prevent too strong a current of air from the brush-cylinder in the back part of the cleaner.

1" 1' represent double doors, hinged to the side boards,hh,neartheirlower edges and closin g on the lower edge of the center board, 4.

A hook is secured to one of the doors, which engages with a staple in the other, whereby the doors may be securely closed. AQreceptaole is thus formed for the sand and trash forced 8 5 by the current of air from the brush-cylinder through the openings between the slats, which may be removed when desired.

8 represents a mote-board, sliding in inclined grooves in the inner faces of the front ends of 0 the side boards, h It. When the mote-board s is drawn forward or raised a part of the motes lying between and below the saw and brush-cylinder are intercepted by the mote-board and prevented from dropping down to the bottom of the gin, as they otherwise would do, and are carried by the current of air over the closed slats is into the lint-room, and when the moteboard is pushed back the motes not intercepted by the mote-board fall down to the bottom of too the gin.

By this construction, the cleaner forming the bottom part of the gin-flue, when the slats are opened by the thumb-nut, the current of air generated by the brush-cylinder in the operation of the gin will carry the sand, dirt, and trash through the openings between the slats, which may be adjusted as desired, into the receptacle below the slats,' whence it may be removed through the double doors, the cleaned cotton passing over the top faces of the slats into the lint-room.

By the use of our cleaner those who run public gins can suit any customer by ginning his cotton just as he desires it. The object of the cleaner is to remove from the cotton all sand, dirt, motes, and trash. Still they can be thrown in with the 1int, if desired, without removing the cleaner, by closing the slats and raising the mote-board; or they can all be removed and cause very dirty cotton to be thoroughly cleaned, thereby greatly enhancing the value of the cotton.

We claim as our invention- 1. In a'cotton-gin attachmentlocated beneath the brush-cylinder, the combination of the frame It z'and slats k,journaled in the frame and forming the bottom of the gin-flue, with the rod 1, attached to the slats, and means, substantially as described, for adjusting the openings between the slats, substantially as described, and for the purpose set forth.

2. In acotton-gin attachmentlocated beneath the brush -cylinder, the combination of the frame h '5, having slats k journaled therein and forming the bottom of the gin-flue, with the rod 1, secured to the slats, screw 0, spiral spring frame h t and slats 7c,journaled in the frame,

with the center board, q, substantially as described, and for the purpose set forth.

4. In a cotton-gin attachmentlocated beneath the brush cylinder, the combination of the frame h 2', provided with inclined grooves and slats k, journaled in the frame, with the sliding mote-board 8, whereby, when the moteboard is raised and the slats closed, the motes will be carried over the slats into the lint-room, substantially as described.

5. The combination, with the frame h t and slats k, journaled in the frame, of the center board, q, and a receptacle under the slats provided with doors 1' r, substantially as described and for the purpose set forth.

6. The cotton -'gin attachment herein described, composed of the tapering side boards, h, and end board, 1', slats k,journaled in the side boards, rod 1, attached to the under faces of the slats, screw 0, spring 19, thumb-nut t, center board, q, and doors 1" 1, substantially as described, and for the purpose set forth.
